F216: No connection with base station (Thermostat RF only)

Fault indication Fault code F216

w and c are lite up

Display text Wireless communication fault.

Solution Check whether the base station for the boiler is on and is functioning

correctly (consult the transmitter manual if necessary). If there is no

connection between the thermostat and base station, then restore the

connection as follows:

- Put the base station in connection mode. Consult the base station

manual for this.

- On the thermostat select Menu > Settings > Users > Connection.

If this does not solve the problem, look for another location for the

thermostat and/or base station or remove “obstacles” that could interfere

with the RF signal.
